Photoshop Elements Color Settings

OK, it's probably something simple, but this is driving me a little bit crazy. My monitor is calibrated with an Eye-One calibration device, but between the Photoshop Elements RAW editor, regular editor and Windows XP image viewer. Below is an example of what I'm talking about. The two Elements editor windows are pretty close in this example, but you can see the XP viewer is very different. It's much darker and has more of a green tint. When I print my images, the color is usually pretty close to what Elements is showing me, but the image is significantly darker, like the image on the top right.

Dark printing may be indicative of a too-bright screen. What luminance target did you set when calibrating?

Well, the first question first -- do you have a way of ensuring that the image you Save As is in sRGB? That is a pretty frequent cause of real noticable shifts in color between Photoshop and a generic viewer.

Windows P&F viewer is not color managed.
It doesn't use the monitor profile, so it will display wrong.

+1 to what René says. Trust what you see in PS Elements.
